97' Navigator Twin Volvo Penta TAM071 & Kohler Generator Results

97' Navigator Yacht - Twin Volvo Penta TAM071s & Kohler Generator

This testimonial from Timothy L. Dahlin documents Cerma STM-3 treatment results on a 97-foot Navigator yacht equipped with twin Volvo Penta TAM071 diesel engines and a Kohler generator.

Vessel Information

  • Boat: 97' Navigator Yacht
  • Engines: Twin Volvo Penta TAM071 diesels
  • Generator: Kohler Genset
  • Treatment: Cerma Marine Engine Treatment with STM-3

Results After Cerma Treatment

Reduced Cold Start Smoke

The engines smoke less during warm-up compared to before treatment - a sign of improved combustion and better cylinder sealing.

Eliminated Fuel Residue in Exhaust

Prior to treatment, fuel residue was being dumped into the water from the starboard engine exhaust. After Cerma treatment, this problem completely went away - indicating cleaner, more complete combustion.

Why These Results Matter

Before Cerma After Cerma
Normal cold start smoke Reduced smoke during warm-up
Fuel residue in starboard exhaust No fuel residue - clean exhaust
Incomplete combustion Improved fuel burn efficiency

What Cleaner Exhaust Indicates

When fuel residue disappears from marine exhaust, it demonstrates:

  • Better cylinder sealing – Fuel burns completely instead of escaping unburned
  • Improved ring seal – Less blow-by and oil contamination
  • More efficient combustion – Better fuel economy potential
  • Reduced environmental impact – Cleaner operation in marine environments

About Cerma Marine Treatments

Cerma STM-3 Technology uses nano Silicon Carbide to create a permanent ceramic barrier on metal surfaces. This improves cylinder sealing, reduces friction, and promotes more complete combustion - explaining why fuel residue problems disappear after treatment.
